CZ, Vysočina – Sedlice Water Reservoir

Published: 17.6.2021
The Sedlice waterworks is a dam reservoir located on the Želivka river near Humpolec in the Vysočina region, specifically below the confluence of the Hejlovka and Jankovský streams. The described area belongs to the geomorphological area Českomoravská vrchovina, district Humpolecká and Želivská pahorkatina. From a geomorphological point of view, the valley of the Želivka River has an erosive character, in some places accumulative-erosive, which means that in some parts of the river, washed-out material accumulates. The valley is medium deep with a narrow floodplain.

The reservoir was built during the years 1921–1927 according to the project of Josef Řeřichy. It is one of the oldest dams in the Czech Republic. The main significance of the Sedlická dam lies in the capture of alluvium that would otherwise get into the Želivka - Švihov reservoir, which serves as a water reservoir for Prague and is sometimes used for recreational purposes in summer. However, it often has poor water quality in the summer months, so unfortunately swimming is not highly recommended in some terms.

In the cadastre of the village there are about 230 holiday cottages and cottages. There are three tourist signs by the dam, after which you can get, for example, to the approximately 8 km distant Humpolec or Želiva, Červená Řečice or Pelhřimov. The whole area is located in a quiet recreational area and during the summer season you will find in the vicinity, for example, a few stalls with refreshments. The area is suitable for hiking and for those who are looking for not very demanding routes. From the top of the magnificent dam is a beautiful view on both sides. When there is little water flowing through the dam, it is possible to go down below it and enjoy the view from the bottom up.

The dam listed on the national register of historical sights is 118 meters long in the crown and is built of quarry stone. The brick dam reaches a height of 11 meters. The lake created behind the dam reaches a depth of up to 15 meters and its area is about 40 hectares. The dam can hold up to 2.3 million cubic meters of water in a maximum volume. The reservoir is therefore not only used for recreational purposes, but is also used for hydropower. The length of the swell of water retained by the dam is less than 3 kilometers. The average long-term annual flow to the tank profile is approximately 2.58 cubic meters per second.
